用超声波测距的四旋翼无人机三维防撞系统设计
Three-dimensional Anti-collision System of Quadrotor Based on Ultrasonic Ranging
摘要
Abstract
Aiming at the frequent collisions of the quadrotors,a three-dimensional anti-collision system is proposed,which is based on the ultrasonic ranging.As an indirect range measurement,the ultrasonic ranging system collects three-dimensional ranges between the quadrotor and its surrounding obstacles.Through processing the three-dimensional ranges,the microcontroller controls the hovering sig-nal and the cut-offs of remote signal for autonomous anti-collision of the quadrotor.This system design is validated by the field experi-ment,which meets the anti-collision requirements.It is light in weight,small in size,high in ranging accuracy,reliable in safety.关键词
